South East (Fujian) Motor Co Ltd, commonly known as Soueast, is a joint venture between Japanese Mitsubishi Motors, Chinese Fujian Motor Industry Group, and Taiwanese China Motor Corporation.

东南汽车诞生于1995年，由福建省汽车工业集团有限公司与台湾最大的汽车企业裕隆集团所属中华汽车公司共同组建，目前东南汽车的股比结构为福汽、三菱、中华分别占股50%、25%和25%。在东南汽车现有业务中，包括两大品牌——外方品牌“三菱”与中方自主品牌“东南”。

相关数据显示，今年 2012 1-8月，三菱品牌轿车累计销量达17418辆，约占东南旗下轿车销量的29%；而自主品牌菱悦累计销量为43615辆，远远超过三菱。此次V5菱致的上市同样也被寄予了厚望，东南汽车总经理左自安表示，希望V5菱致今年的销量能够突破2万辆。在微增长的大环境下，V5菱致能否在3个多月里实现预期的销量，东南销售部部长易善佑表示，2万辆很有挑战，但还是值得期待的。

Located in Fuzhou, Fujian Province, China, it builds Chrysler models, minibuses, and Chinese-market versions of Mitsubishi sedan and MPV models for the Chinese market.

Its cars are license-built versions of Mitsubishi and Chrysler designs[citation needed] some of which bear the Mitsubishi brand. While Mitsubishi-branded models are among it product line, own-brand vehicles are as well. Mitsubishi will enter a new, equally-owned joint venture with Guangzhou Automobile Group but keep an ownership in Soueast, too.

As of early 2011 per year whole vehicle production capacity stood at near 180,000, but this was set to rise to 300,000 as construction was ongoing.
